Optical contrast enhancement

Optical contrast enhancement is a general term in imaging sciences describing techniques, agents, or computational methods that increase the visual distinction between different tissues, organs, or cellular components during optical imaging, such as microscopy or medical scans. This may involve the use of fluorescent probes, phase contrast, differential interference contrast, darkfield, or polarization methods in microscopy, application of contrast agents in medical imaging (e.g., radiology, MRI, CT, optical coherence tomography), or digital image post-processing. These techniques do not represent a molecular or pharmacological target, but instead are crucial methodologies for advancing basic research, diagnostics, and clinical medicine by enabling clearer visualization and differentiation of biological structures.
